The gamesTM Website has excerpts from an upcoming interview with Ron Gilbert where the former LucasArts designer discusses the idea of returning to the beloved Monkey Island franchise. He says he'd want to this on his own terms, but doesn't envision being able to pile up enough loot to tempt George Lucas into parting with the IP. He lightheartedly suggests a nine-figure Kickstarter might do the trick:

“I don’t know the backstory about how Al Lowe got the rights to do Leisure Suit Larry, or any of these other games.” says Gilbert, “but the problem with the Monkey Island stuff is that LucasFilm hoards intellectual property. And George does not need any more money, right? I think if I showed up at their doorstep with a briefcase full of ten million dollars, they would not sell me the license. I think it would have to be an obscenely absurd amount of money to pry that license away from them. So yeah, I don’t think Kickstarter would ever” he trails off before adding, “I mean, maybe I should start a Kickstarter for a hundred million dollars, to buy the Monkey Island license. You never know!”
